लिटः त-
Pāṇini leaves out words that carry over from earlier sūtras. Expand to see the rule as a reader actually understands it.
लिटः त-
Replace liṭaḥ ta-jhayoḥ with eś-irec. Inherited words (anuvṛtti) may add further conditions.
Commentary
The words एश् and इरेच् are the substitutes of ट and झ respectively in the लिट् (Perfect Tense).
The श् of एश् indicates that it replaces the whole of the affix त 1.1.55. The च् of इरेच् is for the sake of accent 6.1.165. Thus पेचे, पेचाते पेचिरे । See the foregoing table of tenses for the Atmanepada.
